“The 20s were full of passion”
Just as people often say, Seong-Jun is a guy full of sexual desire, hiding a secret that he has never shared with anyone. In fact, he masturbated while watching last year's idol star Jang Min-young's fancam.
One night, while drunk, he took his friend Geumji, who fell asleep after their first kiss, to her house. Startled by Geumji's mother's beauty, Seong-Jun tries to hide his state of excitement but is ultimately unable to subdue his desire.
Seong-Jun, who has never experienced such desire for any woman other than Jang Min-young, suggests to Geumji that they should drink alone together again… What will Seong-Jun be?
